MARSHFIELD, Wis., Monday, April 20, 2026 — Wildwood Zoo Announces the Passing of Star, Beloved Mountain Lion.
The City of Marshfield Parks & Recreation Department announces with deep sadness the passing of Star, the resident mountain lion at Wildwood Zoo. Star was 17 years old at the time of her death and considered extremely geriatric for her species. She would have celebrated her 18th birthday this June, an age few mountain lions reach, either in the wild or under human care.
Star had been a cherished member of the Wildwood Zoo family for many years, admired by visitors and staff alike for her quiet strength and dignified presence. She arrived at our park back in 2008, with her brother Thunder, who passed approximately two years ago. In recent weeks, animal care staff observed changes in her behavior, including a decreased appetite and lower activity levels. Out of an abundance of caution, a comprehensive veterinary examination was scheduled.
During the exam, while under anesthesia, Star did very well, and her x-rays showed regular function and promise. Her blood tests ran fine except for a high white cell count. We treated her with antibiotics and waited for her to improve. Unfortunately, she did not, refusing her diet and medication over several days. Given her advanced age and underlying health concerns, the difficult but compassionate decision was made to humanely euthanize her. This decision was guided by a commitment to her quality of life and to prevent further distress or suffering.
Like many senior animals, Star had several age-related conditions that had been carefully managed over time, including arthritis and declining organ function. Despite these challenges, she continued to enjoy her days in familiar ways—resting in sunny spots, purring and squeaking at her neighbors, and engaging with enrichment provided by her caretakers.
Star’s longevity is a testament to the dedicated care she received throughout her life at Wildwood Zoo. While her loss is deeply felt, the staff takes some comfort in knowing she lived a long and well-supported life. A comment from Zoo Manager, Kyle Kirk, “Like a lot of you, I grew up with Star. I was eight years old the first time I’d seen her, and no doubt she’s had a large impact on the trajectory of my life. We remain resolute in our dedication to providing an environment where that kind of connection between humans and animals can happen. Her service as ambassador to her species and to our community will be sorely missed”.
The Parks & Recreation Department extends its gratitude to the community for its continued support during this challenging time. Star will be remembered for her grace, resilience, and the lasting impression she made on all who had the opportunity to see her.
